UI change in the programming feature? (read below)
Received mine recently (3D) Installed a regular Alkaline primary cell and it worked great, real nice tint - very warm neutral, switch works fine and all modes are working. 
The programmable function is also working, but slightly different than described in the OP and earlier posts (the user manual still has nothing about programmable output levels) I first used the instructions from the OP, but these instructions posted in the Discussion thread also worked, except for double tap to exit (had to do a long press to exit):
However for mine there were only 3 programmable modes instead of 4, after I set levels for 3 modes it just goes to high and is no longer auto-ramping, it just remains steady on high, then a single click to strobe, then long press to exit.
I also posted about this in the discussion thread and someone else who ordered one in December replied theirs also had only 3 modes that were programmable. (I ordered mine on Dec. 19th) So it appears they may have changed it to remove programming for HI mode. I’m wondering if that was because when it first came out a few people reported a lower than advertised maximum output, only to discover the default programming for HI wasn’t set to the maximum level.
Can anyone else who also ordered one recently confirm this?
